Abstract
A human condition evaluation system, of which bio-signal analysis means includes a bio-signal peak value detection means for detecting a peak value for each cycle of an original waveform of a bio-signal data, and a power value calculation means for calculating a difference between the peak value at an upper limit side and the peak value at a lower limit side for every prescribed time range using respective peak values obtained by the bio-signal peak value detection means to thereby set the difference as a power value, is structured to determine a predictive signal for falling asleep from an active state into a sleep state. Different from conventional human condition evalution based simply on a Lyapunov exponent as an indicator, a new human condition evaluation system based on a functional status of an energy generation system of the living body is provided.
